i MACHINE FOR FINISHING SKEWER`BLANKS AND THE LIKE.

Application filed July 3, 1915.

To all lwhom it may concern:

Be it known that I, AMos'T. TRUE, a citi zen of the United States,resident of Allens Mills, in the county of Franklin and State of Maine,have made a certain new and useful Invention in Machines for FinishingSkewer-Blanks and the like; and I declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it appertains to make and use the invention,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Figure 1 is a side view of the invention as applied, with parts insection. Fig. 2 is a section on the line 2-2, Fig. 1. Fig. 3 is a detailfragmentary view showing the end abutment or block.

rlhe invention has relation to improvements in machines for pointing orfinishing skewers, having for its object to provide means, bearing uponthe skewer blanks and pressing said blanks against the roughenedperipheral surfaces of the lateral or carrying wheels, that willAprovide the necessary friction to cause the blanks to turn upon saidwheels in the pointing or finishing operation, and yet will be of suchnature as to reduce the friction to the minimum degree required.

This invention is applicable to machinery for finishing cylindricalblanks of various descriptions.

In the accompanying drawings, illustrating the invention, the letters e,e designate the lateral or carrying wheels referred to in my Patent No.970,667, dated Sept. 20, 1910, which is referred to for the generaloperation of the machine, said wheels having roughened peripheralsurfaces o, and it is the endless belt, engaging and carrying theskewers upwardly around said lateral wheels.

Bearing upon the skewer blanks b, and causing them to turn while thecutters u, o, operate upon the butt and point ends of the skewers, are aseries of rollers 2, 2, preferably provided in duplicate series, oneseries being located near each end portion of the blanks, over saidlateral wheels. These rollers are each mounted upon an arm 3, extendingradially of the lateral wheels, the arms engaging perforations 4, 4 of'aro-form top pieces 5 of a frame 6, said rollers and Specification ofLetters Patent.

serial No. 37,999.

the lower ends of the arms fitting between arc-form bottom pieces 7, 7,which limit the lateral movement of the arms and rollers, radial endpieces 8, 8 of said frame limiting any movement of the rollers out ofradial relation, inasmuch as the carrying arms of the rollers are placedclose together, in contact with each other within the frame bounded bysaid lateral bottom pieces and said end pieces. The series of rollers ineach frame 6 is preferably in duplicate, with the carrying arms upon thevoutside in contact with the bottom pieces of the frame and in contactwith each other, and the rollers on the inside in contact with thelateral surfaces of the next or adjacent series, the two series ofrollers in each frame being arranged to lap joints, and suitableabutments or blocks 9, 9 being provided at the ends of the respectiveframes to preserve this lap joint arrangement. The rollers, beingcomparatively small, and lapping joints, will accommodate themselves tothe irregularities of and the spaces between the skewers.

In order to press the rollers downwardly against the skewer blanks inyielding manner, coiled springs 10, 10 are located upon the carryingarms, said springs bearing at their lower ends against collars 11, 11 ofsaid arms, and at their upper ends bearing against the top pieces of theframe.

In the use of this invention, the skewers will be turned as required, asthey are presented to the cutter wheels, and the line of skewers carriedby the belt will move with decreased friction past the pressure devices,the machine being thereby made easy running, its capacityrincreased andthe power required reduced.

The frames 6, 6, or one of said frames, is usually made adjustable, byslot and bolt connections 12, 12, so that the rollers carried by saidframes may be adjusted to suit skewers of varying lengths.

I claim:

1. In a machine for finishing skewer blanks and the like, a carryingbelt for the blanks, a member coperating with the blanks and againstwhich the lower surfaces of the blanks bear, a frame located above saidmember, a series of spring-pressed radial carrying arms in said frame,said arms being in contact with each other at their edges and in contactwith said frame at their outer sides, and a series of rollers carried byand located at the inner side of the planes of said arms, said rollersbeing in contact with each other at their inner sides.

2. In a machine for finishing skewer blanks and the like, a carryingbelt for the blanks, lateral wheels having roughened peripheral surfacesagainst Which the blanks have bearing, a frame located above each ofsaid lateral Wheels, duplicate series of spring-pressed radial carryingarms in each frame, said arms being in Contact with each other at theiredges and in contact with said frame at their outer sides, and duplicateseries of rollers carried by and located at the inner sides of theplanes of said arms,

said rollers being spaced apart from each 15 other at theircircumferential edges and in contact with each other at their innersides. In testimony whereof I affix my signature7 in presence of twoWitnesses.
